Problems connecting to the Internet

If you can’t connect to the Internet, there may be a problem with your cables, your devices, your network settings, or your Internet service.

  • First, try using Network Diagnostics, which can diagnose and resolve most problems.
  • If you have a wireless network, make sure your computer is communicating with the router and that the router is connected to the Internet.
  • If your router is an AirPort Base Station, open AirPort Utility and choose Help > AirPort Utility Help.
  • If your router is from a manufacturer other than Apple, refer to the router’s documentation.
  • Make sure all cables are firmly connected.
  • Make sure all external devices such as modems, hubs, and routers are plugged in, turned on, and have started up completely. Try resetting these devices by unplugging them for a couple of minutes and then plugging them back in.
  • Check indicator lights to make sure your modem or router is registering a connection to the network and to your computer. If an indicator light does not come on, see the documentation that came with the device or contact your ISP.
  • Make sure you have the correct settings for your type of connection. Open the Network pane of System Preferences and check the status of each network service, such as Ethernet, Bluetooth, and AirPort. The network service you are using should have a green indicator and the word “Connected.”

    To view more information about your network service, click to highlight it. For additional help, click the “Assist me” button.

If all of the above are set up correctly and you still can’t connect to the Internet, call your ISP. There may be a temporary problem with the service.

Problems sending and receiving email

OS X includes the Mail app and supports other apps such as Entourage. If you’re experiencing problems with any type of email application, try the following:

  • If you can’t send or receive email messages, first make sure you’re connected to the Internet.
  • If you are using a Mail app from a manufacturer other than Apple, consult the help for that application, or go to the manufacturer’s website.
